Becky leaves Corrie on a high - and should now join Celebrity Big Brother

What Celebrity Big Brother needs now is for Becky McDonald to go into the house.

This series of the reality TV show is heating up nicely, with the housemates having the kind of rows we haven't seen for years.

But what they really need is for Becky to light the blue touch paper and see it really blow up.

There are few better people than the Coronation Street character when you need insults hurled and a good put-down.

Last night she left the cobbles on a much-deserved happy ending, after throwing a few choice words Tracy's way.

"Your shiny new wife's a filthy liar," she told Steve.

I particularly liked the way she called Deirdre 'Dreary'.

Her parting from Roy and Hayley was tearjerking, but I couldn't quite cheer as loudly as I might when she flew off, first class, with new boyfriend Danny to a new life in the Caribbean, declaring: "We're heading for the stars."

This would have had far greater impact if we knew him better. If this was a great love affair which had developed over months or years. If we were finally getting to see two much-loved characters get together, in a Ross and Rachel in Friends way.

Instead we saw Becky leave with a man we've only just met, so when he told her he loved her, it didn't mean much.

Still, let's hope it lasts, eh?

And if it doesn't, Becks should come back and have a go at those awful twins in Celebrity Big Brother. The girs, who made their names posing naked for Playboy and for frequently pulling their pants down in photo shoots, went mad when Denise playfully pulled Karissa's trousers and underwear down.

It was a silly, drunken thing to do but Karissa completely overreacted by storming into the diary room, demanding to see her agent and telling Big Brother: "I'm gonna sue!"

Oh, calm down, dear! You used to be Hugh Hefner's girlfrlend. Very little can get more embarrassing than that. And you really can't claim to be a 'reserved person' .

I reckon Becky would also have had some choice words for bitchy Nicola McLean, who inflamed the row by leaping in on the twins' side. She later revealed she was a 'secret feminist'. Not quite sure what the point of one of them is, or even if she knows what she means.

Throughout all of this, bizarrely, it was Frankie Cacozza who was the mature voice of reason, and I never thought I'd say that.
